Evaluación oftalmológica en niños derivados a un proyecto de rehabilitación en baja visión de un organismo de apoyo social / Ophthalmological evaluation in children referred to a low-vision rehabilitation project of a social assistance agency

INTRODUCCIÓN: Un niño con baja visión (BV) rehabilitado puede tener una educación integral. Objetivo: Estudiar el perfil de los escolares derivados para evaluación a un Proyecto de Rehabilitación en un organismo de apoyo social. PACIENTES Y MÉTODO: Estudio transversal descriptivo de beneficiarios evaluados entre septiembre 2015 y septiembre 2016 en JUNAEB. Se consideró diagnóstico de derivación, agudeza visual monocular (AV) con corrección óptica para lejos (cartillas Feinbloom) y cerca (cartillas Zeiss). Se clasificaron según AV y perimetría. Se consideró éxito de tratamiento lograr AV > 0,4 para le jos y/o cerca con ayuda óptica. RESULTADOS: Se evaluaron 278 escolares. 153 (55%) fueron hombres, 121(43,5%) entre 10 a 14 años. Catarata congénita bilateral, distrofias retinales, alta miopía, atrofia óptica y nistagmus congénito fueron las patologías más frecuentes. 224 (80,6%) se habilitaron con ayudas. 85 (37,9%) presentaron BV moderada y 63 (28,6%) BV severa. 122 (54,5%) presentaban perimetría normal, 68 (30,4%) campo visual (CV) tubular, 19 (8,5%) defecto sectorial del CV y 15 (6,7%) compromiso central del CV. 198 (88,4%) escolares lograron éxito visual de lejos y todos lograron éxito visual de cerca. 48 (17,2%) escolares no pudieron ser rehabilitados, estando asocia dos a una afección neuroftalmológica (41,7%), alto error refractivo (16,6%) o glaucoma congénito (10,4%). 6 (2,2%) casos mejoraron su AV con nueva corrección óptica. CONCLUSIÓN: El éxito obtenido demuestra la necesidad de habilitar visualmente a escolares con BV. Nuestro desafío es mantener este programa y educar al oftalmólogo prestador para una derivación oportuna.

INTRODUCTION: A low-vision (LV) rehabilitated child can receive comprehensive education. OBJECTIVE: To study the profile of school children referred for evaluation to a rehabilitation project in a social assistance agency. PATIENTS AND METHODS and Method: Descriptive cross-sectional study of beneficiaries evaluated between September 2015 and September 2016 in the National Board of School Assistan ce and Scholarships (JUNAEB). The referral diagnosis, monocular visual acuity (VA) with optical correction at far (Feinbloom chart) and close (Zeiss chart) distances were considered. They were classified according to VA and perimetry. Treatment success was considered if VA reaches > 0.4 at far and/or close distances with optical devices. RESULTS: 278 students were assessed. 153 (55%) were men, 121 (43.5%) between the ages of 10 to 14. Bilateral congenital cataract, retinal dystrophies, high myopia, optic atrophy, and congenital nystagmus were the most frequent pathologies. 224 students (80.6%) received optical devices. 85 (37.9%) presented moderate LV and 63 (28.6%) severe LV; 122 (54.5%) presented normal perimetry, 68 (30.4%) tubular Visual Field (VF), 19 (8.5%) sectoral VF defects, and 15 (6.7%) central scotoma. 198 (88.4%) students achieved visual success at a far distance and all achieved visual success at a near distance. 48 (17.2%) students could not be rehabilitated due to a neuro-ophthalmological condition (41.7%), high refractive error (16.6%) or congenital glauco ma (10.4%).Six (2.2%) cases improved VA with a new optical correction. CONCLUSION: This success demonstrates the need to provide low vision aids to schoolchildren with LV. Our challenge is to maintain this program and to educate ophthalmologist for timely referral.

Research advances in low-vision rehabilitation by means of microperimeter biofeedback examination in patients with different macular diseases / 眼科新进展

In macular diseases,there is a typical development of a central scotoma which is responsible for the central visual acuity loss,reading speed reduction and changing in fixation stability.The prevention and treatment of degenerative macular disease have not yet received satisfying functional results.Effectiveness of biofeedback treatment in visual rehabilitation has been evidenced in several studies.The microperimeter can improve their visual abilities and lay the basis for new,more manageable visual aids by using cerebral plasticity and neurosensorial adaptation to the central scotoma of patients with macular diseases.The purpose of this review is to summarize key fmdings on characteristics of central scotoma,the plasticity of human visual system and visual rehabilitation via microperimetry.

A Study of Eccentric Viewing Training for Low Vision Rehabilitation

PURPOSE: The definition of eccentric viewing (EV) is using non-foveal preferred retinal loci (PRL) for viewing. The purpose of the present study was to investigate the clinical effect of EV training for low vision rehabilitation in patients with central scotomas. METHODS: The direction of EV was monitored in 30 low vision patients with central scotomas by moving the patient's view. The PRL was found by using a direct ophthalmoscope and retinal camera; the preserved visual field was identified using a kinetic visual field analyzer. The relationships between EV, PRL, and visual field were evaluated. The patients and their guardians were educated regarding EV. After 2 weeks of self-training, maintenance of EV was checked and changes in best-corrected visual acuity (BCVA), reading speed, and satisfaction questionnaire were evaluated. RESULTS: A relationship between EV, PRL, and visual field was in accordance in half of the patients. There were no significant differences in demographics and basic visual characteristics in patients where the relationship was not in accordance. EV was maintained in two-thirds of the patients, but there were no significant differences in demographics and basic visual characteristics in patients who discontinued EV. There were no significant improvements in BCVA; however, reading speed and the satisfaction scores increased significantly with EV. CONCLUSIONS: The direction of EV was effectively detected by convenient access using an inexpensive method. Functional vision and satisfaction significantly improved following EV training. EV training can be used as an effective method for low vision rehabilitation in patients with central scotomas.

Low vision aid in exudative macular degeneration treated by photodynamic therapy and thermal laser photocoagulation / 国际眼科杂志(Guoji Yanke Zazhi)

· AIM: To determine the efficacy of low vision rehabilitation (LVR) in patients with age related macular degeneration (AMD) treated by photodynamic therapy (PDT) compared to those treated by thermal laser (TLP).examining the files of 42 patients (42 eyes) with AMD who had been treated either by TLP (Group 1) and PDT (Group 2). Once AMD was considered to be inactive they underwent visual rehabilitation in the LVR Unit in order to increase their ability for distant and near vision.received TLP. Average corrected visual acuity after laser therapy was 0.14 in Group 1, and 0.16 in Group 2. No statistically significant differences were found between both groups before and after laser therapy. Both groups showed improvement after LVR; however, statistically significant differences between both groups were found only for near vision.both PDT and TLP are associated to a decreased visual acuity after treatment, LVR may be more successful for near vision among patients treated by PDT
